Intellij not saving files automatically with X11 Forwarding

I am running a Redhat7 Server with multiple users.  Each user has their own account and home folder, and there is an install of Intellij under each user's home.  The users then login over SSH using Mobiterm (X11 Forwarding-Compatible SSH Client), and run idea.sh, which then opens a UI on their computer.

This works out very well, except for the auto-save features of Intellij.  For some reason, the changes made in the editor are not persisted back to disk on the server until the developer closes Intellij from the client computer.  Only at that point are all of the changes written to disk.  If the internet connection is dropped before Intellij is closed gracefully, the changes are lost.

Is there some additional configuration required to use X11 forwarding with Intellij and support auto-saving?
